Can you encrypt a virus?
An encryption virus gets onto your system and starts encrypting important and confidential documents and files. This makes the files unreadable by the applications that created them. The only way to unencrypt the files is to have access to the encryption key used in the encryption process.
Which virus type uses encryption technique?
A polymorphic virus includes an encrypted payload and a mutation engine. The encryption hides the malicious payload from scanners and threat detection software, which are left to identify the virus by its decryption routine.
Should you encrypt data before transferring it to the cloud or encrypt it after it is stored in the cloud?
Even if a cloud service provider does offer to encrypt files after they arrive on its servers, it is critical that you encrypt data before it’s sent.

Which virus uses encryption to hide its presence?
What is a polymorphic virus? A polymorphic virus is one that produces varied but operational copies of itself. This strategy assumes that virus scanners will not be able to detect all instances of the virus. One method of evading scan-string driven virus detectors is self-encryption with a variable key.
Can polymorphic virus be detected?
The use of complex mutation engines that generate billions of decryption routines make them even more difficult to detect. Polymorphic viruses are usually distributed via spam, infected sites, or through the use of other malware.
Is it smart to keep all your data on the cloud?
